It was working fine when I went to make dinner. When I came back minutes later it had shut itself off. When I pressed the power button, the three lights on the bottom of the computer flash with no sound and nothing happens.
When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?
When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.
Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.
Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.
Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.
No, it doesn't do anything. no beeps, no noise, no fan.
just three lights on the bottom blink three times then nothing.
Remove the Power Cord, Remove the battery, then on the bottom open the memory compartment (usually a screw or two is attached to the cover) and remove one of the memory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.
If the memory test doesn't do anything then maybe your hard drive is dead. But normally the system would tell you that there's a hard drive problem so I'm thinking the drive must be ok. So if the memory chip swap does nothing you've probably have problems with the motherboard.
OK, I just looked up the beep and blink codes. Three blinks means a memory problem. One of your memory chips is probably bad or they just need to be reseated (taken out and put back in securely).

I have already performed all of these tests including taking the computer completely apart to look for loose connections and power input connectivity to motherboard. I have checked all of the memory processes as you have described. When I attempt to boot up the computer there is NO SOUND. Nothing happens except for the three blinking lights. The light where the power cord is connected does NOT light up when the power cord is attached. I have checked the outlet that it is connected to and it is working. I THINK the cord is bad. I will attempt a replacement today with it to find out for sure.
